The goal of the North Dakota Geographic Targeting System for Groundwater Monitoring (GTS) is to assess monitoring priorities for existing glacial drift aquifers, assign monitoring priorities to new aquifers, and update the methods of the GTS to include new geographic information system (GIS) capabilities. The GTS is a tool used by the Agicultural Ambient Groundwater Monitoring Program to assign monitoring priority to shallow aquifers. This layer represents the map in Attachment 3 of the "North Dakota Geographic Targeting System For Groundwater Monitoring" dated October 2019. The report is published by the North Dakota Department of Environmental Quality, Division of Water Quality. This layer was updated in January 2021 to include 68 new aquifers that were scored in the "2021 Addendum to the 2019 North Dakota Geographic Targeting System For Groundwater Monitoring" (January 2021) and to match North Dakota State Water Commission aquifer delineations and names as of January 2021. |

<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>The North Dakota Geographic Targeting System for Groundwater Monitoring (GTS) was first conducted in 1997 as a method of assigning monitoring priority to shallow aquifers. The decision to update the monitoring priority was made in 2015 in response to changing aquifer boundaries, land use, and groundwater appropriation. The analysis was complete and first published in 2018. Additional update to address water levels in confined aquifers was published in October 2019. </SPAN><SPAN>In January 2021, 68 new aquifers were added to the layer that were included in the "2021 Addendum to the 2019 North Dakota Geographic Targeting System For Groundwater Monitoring". Four aquifer names were also updated and all aquifer boundaries were updated to match North Dakota State Water Commission aquifer delineations and names as of January 2021. The January 2021 addendum report is available online at </SPAN><A href="https://deq.nd.gov/publications/wq/1_GW/GeoTargetSys/2021_GTS_Addendum.pdf"><SPAN>https://deq.nd.gov/publications/wq/1_GW/GeoTargetSys/2021_GTS_Addendum.pdf</SPAN></A><SPAN>; The completed 2019 report is available online at </SPAN><A href="https://deq.nd.gov/publications/wq/1_GW/GeoTargetSys/2018_GTS/2019_GTS_Report_October2019.pdf"><SPAN>https://deq.nd.gov/publications/wq/1_GW/GeoTargetSys/2018_GTS/2019_GTS_Report_October2019.pdf</SPAN></A></P><P><SPAN>The GTS consists of three components: Vulnerability, Sensitivity, and Risk. Each component is given three values: a Value, a Score, and a Rating. The Value is the numeric representation of each component. The Score is a number ranging from 1 to 3, and is assigned based on the Value range. A Rating can be LOW, MODERATE, or HIGH, and correlates to a Score rating of 1, 2, or 3 respectively. </SPAN></P><P><SPAN><SPAN>The score of each component is added together to achieve a total monitoring score ranging from 3 - 9. The Total Monitoring Rating is then assigned based on this score: 3-4 (LOW), 5-7 (MODERATE), 8-9 (HIGH). </SPAN></SPAN></P><P><SPAN><SPAN>This dataset has value, score, and rating fields for each component, total monitoring score, total monitoring rating, and DRASTIC and Pesticide DRASTIC value fields. </SPAN></SPAN></P><P><SPAN><SPAN>COMPONENT RATINGS</SPAN></SPAN></P><P><SPAN><SPAN>Vulnerability</SPAN></SPAN></P><P><SPAN><SPAN>Pesticide DRASTIC Value - Score - Rating</SPAN></SPAN></P><P><SPAN><SPAN>0-129 - 1 - LOW</SPAN></SPAN></P><P><SPAN>130-159 - 2 - MODERATE</SPAN></P><P><SPAN><SPAN>160+ - 3 - HIGH</SPAN></SPAN></P><P><SPAN><SPAN>Sensitivity</SPAN></SPAN></P><P><SPAN><SPAN>Production (in dollars per farmed acre) Value - Score - Rating</SPAN></SPAN></P><P><SPAN><SPAN>0-202.14 - 1 - LOW</SPAN></SPAN></P><P><SPAN><SPAN>202.15 - 356.91 - 2 - MODERATE</SPAN></SPAN></P><P><SPAN><SPAN>356.92+ - 3 - HIGH</SPAN></SPAN></P><P><SPAN><SPAN>Risk</SPAN></SPAN></P><P><SPAN><SPAN>Appropriated acre-feet per square mile - Score - Rating</SPAN></SPAN></P><P><SPAN><SPAN>0-1.243 - 1 - LOW</SPAN></SPAN></P><P><SPAN>1.244-33.51 - 2 - MODERATE</SPAN></P><P><SPAN><SPAN>33.52+ - 3 - HIGH</SPAN></SPAN></P><P><SPAN><SPAN>Total Monitoring Score</SPAN></SPAN></P><P><SPAN><SPAN>Vulnerability Score + Sensitivity Score + Risk Score = Monitoring Score (Monitoring Rating)</SPAN></SPAN></P><P><SPAN><SPAN>3-4 (LOW)</SPAN></SPAN></P><P><SPAN><SPAN>5-7 (MODERATE)</SPAN></SPAN></P><P><SPAN><SPAN>8-9 (HIGH)</SPAN></SPAN></P><P><SPAN>Dataset Finalized: January 2021</SPAN></P></DIV></DIV></DIV> |
